Inferred Mineral Resources must not be included in the economic analysis, production schedules, or estimated mine life in publicly disclosed Pre-Feasibility or Feasibility Studies, or in the Life of Mine plans and cash flow models of developed mines. Key points: Inferred Mineral Resources must not be included in the economic analysis, production schedules, or estimated mine life in publicly disclosed Pre-Feasibility or Feasibility Studies, or in the Life of Mine plans and cash f; The assay results from grab samples from the Kronbauer shaft returned from 0.31g/t to 73.70 g/t gold and the samples from quartz stockpile from the Rodrigues shaft returned 11.50 g/t and 40.50 g/t gold; In addition to the grade capping practice, Micon also performed a special interpolation run called Pass Zero, to restrict very high-grade assay results and honour their values in the block model, this run was capped at 7; The assay results from grab samples from Kronbauer shaft returned from 0.31 g/t to 73.70 g/t gold and the samples from quartz stockpile from Rodrigues shaft returned 11.50 g/t and 40.50 g/t gold; Figure 11.12 Scattered Plot of the Original Assay Results and the Pulp Duplicate Results Only 2 of the failed duplicates have values above the mineralization threshold (2 g/t Au), used for outlining the solids of the pot; In addition to the grade capping practice, Micon also performed an special interpolation run called Pass Zero*, to restrict very high grade assay results and honour their values in the block model, this run was also capp. This brief is based on the cited source artifact and is intended as a research entry point, not a replacement for the original source or EGM canonical data tables.
